TIRE.

Appucatian mea august as, 1912. serial No. 716,745.

T all whom t may concern Be it known that I, LYMAN H. FERGU- soN, acitizen of the United States, residin at Ithaca', in the county ofTompkins an State of New York, have invented new and useful Improvementsin Tires, of which the asis now common practice.

Another object of the invention is to pro vide a structure of this typeembodying a plurality of separating partitions between which are locatedindependent pneumatic` tubes removable through the felly of the wheeland replaceable in a like manner.

Still another object of the invention is to provide a tire having aplurality of independent pneumatic` ltubes removable 26 through thefellyand supported around the4 aperture by the valve tube itself and by a yclip removably connected to the felly.

Further obyects of the invention will appear as vthe following specificdescription is 80 read in connection with the accompanying drawings,which form a part of this application and in which Figure 1l is a sideelevation partly in 'section. Fig. 2 is a transverse sectional View onthe line 2-2 of Fig. 1. Fig. 3 is a longitudinal horizontal sectiontaken on the line 3-3 of Fig. 1. Fig. 4 isa detail perspective viewlooking from the under side of the felly.

Referring more particularly to the drawf ings, l represents a fellywhich is connected to the hub, not shown, by the spokes 2 and hassecured upon its outer periphery a tire receiving rim 3, provided as isusual with depending flanges 4 to straddlethe felly.

Mounted `upon the rim 3 is .an annular tire body 5 constructed similarlyto the ordinary pneumatic shoes and-being provided with laterallyextending annular flanges 6, which ,engage the rim?, and are adapted tobe'clamp'edthe'reonby means of the annular rings 7 andthe clips 8. Theseclips are held in position straddling the ring and the rim 3,yby,r1ieans of, bolts 9 which pass `v threugh" the clips and through theflanges 6.

the double key-hole openings 1n the. felly,

As before stated the tire isconstructed in the manner of ordinarypneumatic shoes, being open on its under side to permit open ing thetire for removal ofthe core of the mold and for any other suitablepurpose. Connected to one "half of the tire and extending entirelyacross the interior of the same is a partition 10 and a similarpartition 11 is connected to the opposite half of the tire and extendsacross the interior of the same in the opposite direction. The free endsof these partitions are held against lateral displacement by beingarranged between the .connected portion of the opposite partition andbetween ribs 12 formed integrally with and projecting inwardly from thesides of the body. These partitions ,are arranged in pairs oflalternatelyextendin partitions 'and form compartments 13 forindependent pneumatic tubes 14. v. i

Adjacent each compartment the felly l, rim 3, and the body of the tire 5are provided with registering apertures 15, 16 and 17 respectively, allof which are of double key-hole formation and are of suflicient size to.permit the insertion ofthe tubes 14. These tubes are reinforced aroundthe valve nipple 18 by means of strips 19' and 20, the latter beingarranged on the outside ofthe 85 tube and extending the full lengththereof.

Valve tubes 18 are connected to the tubes 14 in any suitable orapproved'manner and preferably have the shoulder lon the outside of thepneumatic tube formed. so as to vfit rim and tire. Adjacent the outerend of the tube there is formed va shoulder 21 and a reduced nippleextension 22 which is of such size as to pass conveniently through aretaining clip 23 removably' secured to the felly by means of the bolts24.

It will be noticed from the foregoing that the pneumatic tubes may beconveniently removed and replaced throughthe openings in the tire, -rimand felly and that when in .position in the body are held againstblowing out through the openings by means of the valve tube itself andthe clips 23 which form abutments for the shoulders 21. 10

What is claimed is 1. In a device .of the character described, acombination with an. .apertured felly, of a tire casing secured to saidfelly and having` apertures therein registering with the l able clipsdisposed on the felly and having a perforation therein regtures, andsaid collar being adapted to engage said clips for holding said nippleWithin said aperture.

apertures in said felly, a series of partitions arranged Within saidcasing and forming compartments therein, pneumatic tubes disposed Withinsaid compartments, a valve nipple projecting 4from said pneumatic tubesand extending through said apertures, perforated clips removably mountedupon said felly, shoulders formed on the free ends of said nipples andWithin said apertures of the felly and being adapted to engage saidclips to prevent the ,tubes from blowing out of said casing.

2. In com ination with an apertured felly, a casing mounted upon saidfelly and provided With a series of vchamers having an aperture thereinregistering with the apertures of said felly, removunderside of saidfelly, a casing mounted upon the felly and having apertures thereinregistering with the apertures of said felly, removable clips disposeduponthe underside of said felly 'each having a perforation thereinregistering With an aperture of the-felly, said perthe felly, apneumatic tube Within said casing, valve nipples projecting from saidtube and extended through said .apertures and said perforations, anenlargement formed near the lower ends of said valve nipples andsubstantially -of the same size as said apertures, and said enlargementbeing I adapted to engage said clips for holding istermg with one ,'ofsaid apertures of the I said nipples Within said apertures.
